Secret Ingredient to Photorealism / dynamic range?

- I think I have the same issue in octane, simply put the dynamic range isn't hight enough, we can't crank up the sun without burning and clipping the render, there never seems to be enough lighting coming out from the sun, and we alsways have to do some crazy tricks..

srgb is supposed to be the worst color management to view renders

- I have some idea that you could achieve this with a 16bit image in photoshop where the dynamic range is much higher and we can control it in different ways, maybe it's just up to the colour space used.. like in blender..

- anyaway, I would love detailed information on this topic

Hi

Think your link is bust?

try

Great article.

yeah, damn..

Also nobody cares here, I think we need some better update to color space.. renders get burned too fast

When I learned lightning in maya software 10 years ago(?) it had shittier dynamic range than renders can offer today, the trick I learned from Jeremy Engleman was to do a HDRI with a linear workflow.
So you do the same thing you would with a regular dslr, take several shots with different exposure levels. 8 exposure levels normally kick any real life camera.
Since this is a octane imager function it won't really add any render time, but there will be some time added in post.

1. Linear workflow (get that gamma!)
2. Set output to 32-bit openEXR (inorder to capture as much output data as possible)
3. Take several exposures
4. Stack the dynamic range https://helpx.adobe.com/photoshop/using ... mages.html
5. Color correct

Excellent tips, thanks.

Will have to give it a try.
